Ok, I did a little searching around, but my search fu isn't what it use to be, so i couldn't seem to find an answer. In GB 1 the trap cord is it always split loom, or is it sometimes a smooth cord? I was thinking it was both, but wanted to be sure. Also I saw some threads stating the average length of trap cord in GB1 was around 10 foot, anybody know if that is right or where that number came from?
